Justin I

The extent of the Byzantine Empire under Justin I is shown in brown. (The light orange shows the conquests of his successor, Justinian.)

Justin endeavoured to cultivate client states on the borders of the Empire, and avoided any significant warfare until late in his reign.[24]

In 497 Anastasius had agreed with Theoderic, the Ostrogothic king of Italy, that he would rule Italy as Anastasius' deputy. This preserved Italy as nominally a part of the Empire, and neutralised a potentially dangerous neighbour. The arrangement suited Theodoric, as the Ostrogoths were a small aristocratic minority in Italy and the blessing of Constantinople helped reconcile the majority of the population to their rule. The feelings of the majority of Italians towards the Empire were mixed, as Anastasius was a Monophysite, while they were Chalcedonian. The Ostrogoths were Arians, and there was a tendency to consider both them and Monophysites as different breeds of heretics. With a strongly Chalcedonian emperor on the throne and the Italian-based papacy formally healing the rift the situation became less stable. Initially relations were friendly. Theodoric's son-in-law Eutharic was appointed consul in Constantinople in 519 and confirmed as Theodoric's heir. Eutharic died in 522, by which time Justin's policies, possibly influenced by Justinian, had become more anti-Arian. In 526 Theodoric died, leaving Eutharic's ten-year-old son Athalaric as heir to the throne.[25][26]

A number of initiatives in respect of neighbouring states were founded on religious motives, and were usually developed by Justinian as he assumed more power towards the end of Justin's reign. Kaleb I of Aksum was probably encouraged to aggressively enlarge his empire by Justin. Contemporary chronicler John Malalas reported that Byzantine merchants were robbed and killed by the Jewish King of the south Arabian Kingdom of Himyar, causing Kaleb to claim, "You have acted badly because you have killed merchants of the Christian Romans, which is a loss both to myself and my kingdom."[27] Himyar was a client state of the Sassanian Persians, perennial enemies of the Byzantines. After Kaleb invaded Himyar around 523, Justin saw what is now Yemen pass from Sassanian control to the rule of an allied Christian state.[27]

A number of small states on the borders of the Byzantine Empire and of Sassanian Persia were constant areas of contention between the two powers. The Georgian Principality of Iberia was in the Sassanian sphere of influence, but was Christian. Iberian bishops were sent to Antioch in the Byzantine Empire to be consecrated. Vakhtang I of Iberia was encouraged into war with the Sassanians. A "fervent Christian", his religious policies were "part and parcel of his larger strategic aims".[27] After a lengthy struggle he was defeated and Iberia subjugated as a Sassanian province in 522.[27]

Lazica was another border state; it was Christian, but in the Sassanid sphere. Its king, Tzath, wished to reduce Sassanid influence. In 521 or 522, he went to Constantinople to receive the insignia and royal robes of kingship from Justin's hand and to make his submission. He was also baptized as a Christian and married a Byzantine noblewoman, Valeriana. After having been confirmed in his kingdom by the Byzantine emperor, he returned to Lazica. Shortly after Justin's death the Sassanids attempted to forcibly regain control, but were beaten off with assistance from Justin's successor.[28][29]

In 524 the Sassanid emperor Kavadh I approached Justin asking that he formally adopt his youngest son, Khosrow, in order to secure his succession over his elder, but less favoured, brothers. Justin was agreeable, but, aware that being childless himself an adopted Persian son would have a claim on the Byzantine throne, offered adoption according to barbarian custom. The Persians were insulted and broke off all negotiations.[30] In 526, the Byzantines raided Persian Armenia at Justinian's initiative. Justinian was increasingly taking control of policy from his aging uncle. The raiding parties were led by two of Justinian's up-and-coming military protégees, Sittas and Belisarius. The raids achieved little, other than to make a statement of intent.[26]

Justin's reign is noteworthy for the resolution of the Acacian schism between the eastern and western branches of the Christian church. On ascending the throne Justin invited Pope Hormisdas to Constantinople for negotiations. Justinian sent a similar, but separate, invitation; said to have been closer to a summons. Hormisdas promptly despatched a delegation to Constantinople with instructions to state the orthodox position rather than to negotiate. Carrying out a policy developed by his nephew Justinian, the future emperor, Justin endorsed Rome's view on the question of the dual nature of Christ. On 28 March 519, in the cathedral of Constantinople in the presence of a great throng of people, a reluctant Patriarch John II accepted the formula of Pope Hormisdas and the end of the schism was concluded in a solemn ceremony.[26]

For the first three years of his reign Justin persecuted the Monophysites, even serving soldiers. Thereafter he adopted a more pragmatic approach. In 523 Justin issued a strict edict against Arianism. Theodoric, King of the Ostrogoths and ruler of Italy, was an Arian himself, as were most Ostrogoths. He despatched Pope John I, Pope Hormisdas' successor, to Constantinople with firm instructions to obtain a policy reversal. John received an exceptionally warm welcome; the population of Constantinople applauded him, Justin laid on celebrations, prostrated himself at the Pope's feet and insisted on being re-crowned by the Pope's hands. John did not succeed in having the edict overturned, it seems that he did not press the matter. On his return to Italy an enraged Theodoric had him flung into prison, where he shortly died.[26][31][32]

Again encouraged by Justinian, Justin increasingly expressed his position as emperor as a religious one. He claimed that "we have been elected to the empire by favour of the indivisible Trinity.[33][34] Edicts were endorsed with "We continuously commit ourselves to all plans and actions in the name of Jesus Christ".[35] In either 519 or 522 Justin abandoned the tradition of depicting pagan symbols on the reverse of his coins and seals. "During the reign, the characteristic identifying the reverse female figure as Victory, a high girdle below the breasts, was substituted by a tunic, therefore identifying the figure as an angel."[24] This was a very public and widespread restatement of the Empire as a Christian state.[24]

The later years of the reign of Justin were marked by increased tension with the Empire's neighbours, especially the Ostrogoths, and the Sassanids. In 526 Antioch was destroyed by an earthquake with an estimated 250,000 deaths. Justin arranged for sufficient money to be sent to the city for both immediate relief and to start reconstruction. The rebuilding of the Great Church and many other buildings was overseen by Ephraim, the comes Orientis, whose efforts saw him replace Euphrasius as the Chalcedonian Patriarch of Antioch. Many of the buildings erected after the earthquake were destroyed by another major earthquake in November 528, although there were far fewer casualties.[36][37][38]

Procopius of Caesarea's Byzantine historia indicate that Justin I's mental faculties had begun to decline in his old age, going as far as to write "the Emperor, as an idiot and advanced in age, caused the laugh of the environment, and was also accused of delays in decisions and inability for his duties."[39]
